`vp_pending` is a flag indicating to wait for `ViewportTexture::_setup_local_to_scene`
to be called. Once this method is called, no matter whether the setup will fail or not,
it needs to be reset to `false`.
When changing `viewport_path`, the `proxy`'s target is changed to a new placeholder.
Add a flag `vp_changed` to prevent calling `setup_local_to_scene` (mainly called by toggling `resource_local_to_scene`) when the target viewport has not changed.
Currently mouse hovering doesn't update the state, when collision objects
or the camera move.
This PR fixes this problem by taking the mouse position from the viewport
and not from a nonexistent previous event.
Since previous events could potentially be a long time ago, their
modifier-key state might be outdated. This PR fetches the current
status of modifier-keys from `Input`.
These changes allow the removal of some class-variables and making
additional simplifications.
When a Viewport is not directly attached to the screen, the
function `Viewport::get_mouse_position` can't rely on
`get_screen_transform`, because that function is ambiguous in
these situations.
In these cases it is necessary to use the mouse position from
the most recent mouse IputEvent.
AnimationNodeBlendSpace2DEditor:
- `!tree` is always false, because it is checked a few lines above
CurveEdit:
- grabbing != GRAB_NONE is redundant
GradientTexture2DEdit:
- grabbed != HANDLE_FROM is redundant
- grabbed != HANDLE_TO is redundant
Viewport:
- index is not used afterwards
- In these cases `gui.mouse_focus` is always valid. Move check to a DEV_ASSERT
- simplify `stopped` calculation
The functionality of `push_unhandled_input` has changed so that it no
longer propagates input events to SubViewports.
This makes it less predictable and it should be deprecated in favor of
`push_input` which provides the same functionality and more.
Also this deprecation simplifies the Viewport-API by reducing the methods
for pushing input events, so that users don't need to worry about when
to use which function in order to insert input events.
A single mouse click can cause multiple actions, which contradicts
the paradigm that a single Input Event should cause only a single
action.
The solution consists of two parts:
1. Physics Picking as the last step during viewport input event
handling, currently doesn't set the event as handled. This PR sets
the event as handled in the case of physics picking.
2. After an InputEvent is processed by a SubVieportContainer, it is
sent to its parent, even if it set as handled within the SubViewport.
This PR adds an additional test to check if the event is handled
before propagating the event to the parent Control.
The associated `ViewportTexture`s will update the `viewport_path`
in time when the `Viewport`'s nodepath is changed (caused by renaming
the node names or moving in the SceneTree dock).
If the target `Viewport` is changed by resetting the `viewport_path`,
the `ViewportTexture`s will be re-setup and emit `changed` signal in
time.
* This notification makes node children management very inefficient.
* Replaced by a NOTIFICATION_CHILDREN_CHANGED (and children_changed signal).
* Changed Canvas code (and similar) to use the above signal, to perform more efficiently.
This PR breaks compatibility (although this notification was very rarely used, even within the engine), but provides an alternate way to do the same.
It is required for the changes in #75627 to be entirely effective.
Fixes#75084.
The clamp_to_embedder setting was added in 8be16e0704,
but was not set on any of the in-editor dialogs.
This patch sets `clamp_to_embedder` on editor dialogs so they cannot be dragged out of the frame.
This also modifies `clamp_to_embedder` so a window is clamped to the bounds of an embedder when
it pops up and when the parent is resized.
This solves the problem, that mouse events get sent to SubViewports
even if they are outside of the visible area of the SubViewport.
This changes makes SubViewportContainer::unhandled_input redundand.
Shortcut Events now need to be distributed via push_input, in order for
them to be able to reach SubViewports.
